Thirty years ago, back in 1983, the biggest hard drives stored about 10MB of data. That’s barely enough to store two or three .mp3 tracks. Now, a typical notebook has one terabyte of storage or nearly 100,000 times more but even this is figure is laughable when you consider how much data we’re generating. According to IBM, every day we’re creating 2.5 quintillion bytes of data and 90% of today’s digital data was created in the last two years.

Even those who are computer savvy still look at data at the gigabyte or terabyte scale but it’s clear we’re moving well past this point. It can get confusing and dizzy so let’s take a brief overview of how we quantify data and put some context on some of the more obscure units of digital information like the petabyte or yottabyte.
